+* MDIO IO device
+
+The MDIO is a bus to which the PHY devices are connected.  For each
+device that exists on this bus, a child node should be created.  See
+the definition of the PHY node in booting-without-of.txt for an example
+of how to define a PHY.
+
+Required properties:
+  - reg : Offset and length of the register set for the device, and optionally
+          the offset and length of the TBIPA register (TBI PHY address
+	  register).  If TBIPA register is not specified, the driver will
+	  attempt to infer it from the register set specified (your mileage may
+	  vary).
+  - compatible : Should define the compatible device type for the
+    mdio. Currently supported strings/devices are:
+	- "fsl,gianfar-tbi"
+	- "fsl,gianfar-mdio"
+	- "fsl,etsec2-tbi"
+	- "fsl,etsec2-mdio"
+	- "fsl,ucc-mdio"
+	- "fsl,fman-mdio"
+    When device_type is "mdio", the following strings are also considered:
+	- "gianfar"
+	- "ucc_geth_phy"
+
+Example:
+
+	mdio@24520 {
+		reg = <24520 20>;
+		compatible = "fsl,gianfar-mdio";
+
+		ethernet-phy@0 {
+			......
+		};
+	};
+
+* TBI Internal MDIO bus
+
+As of this writing, every tsec is associated with an internal TBI PHY.
+This PHY is accessed through the local MDIO bus.  These buses are defined
+similarly to the mdio buses, except they are compatible with "fsl,gianfar-tbi".
+The TBI PHYs underneath them are similar to normal PHYs, but the reg property
+is considered instructive, rather than descriptive.  The reg property should
+be chosen so it doesn't interfere with other PHYs on the bus.
+
+* Gianfar-compatible ethernet nodes
+
+Properties:
+
+  - device_type : Should be "network"
+  - model : Model of the device.  Can be "TSEC", "eTSEC", or "FEC"
+  - compatible : Should be "gianfar"
+  - reg : Offset and length of the register set for the device
+  - interrupts : For FEC devices, the first interrupt is the device's
+    interrupt.  For TSEC and eTSEC devices, the first interrupt is
+    transmit, the second is receive, and the third is error.
+  - phy-handle : See ethernet.txt file in the same directory.
+  - fixed-link : See fixed-link.txt in the same directory.
+  - phy-connection-type : See ethernet.txt file in the same directory.
+    This property is only really needed if the connection is of type
+    "rgmii-id", as all other connection types are detected by hardware.
+  - fsl,magic-packet : If present, indicates that the hardware supports
+    waking up via magic packet.
+  - fsl,wake-on-filer : If present, indicates that the hardware supports
+    waking up by Filer General Purpose Interrupt (FGPI) asserted on the
+    Rx int line.  This is an advanced power management capability allowing
+    certain packet types (user) defined by filer rules to wake up the system.
+  - bd-stash : If present, indicates that the hardware supports stashing
+    buffer descriptors in the L2.
+  - rx-stash-len : Denotes the number of bytes of a received buffer to stash
+    in the L2.
+  - rx-stash-idx : Denotes the index of the first byte from the received
+    buffer to stash in the L2.
+
+Example:
+	ethernet@24000 {
+		device_type = "network";
+		model = "TSEC";
+		compatible = "gianfar";
+		reg = <0x24000 0x1000>;
+		local-mac-address = [ 00 E0 0C 00 73 00 ];
+		interrupts = <29 2 30 2 34 2>;
+		interrupt-parent = <&mpic>;
+		phy-handle = <&phy0>
+	};
